Students in grades 4-8 now have access to a Google Apps account. Within it, they have access to Google Sites, GMail, Google Docs, and more. The difference between a Google Apps account and a general Google Account is that accounts can be administered by the board, and students have an added level of control when it comes to sharing. Students can, for the purposes of school work for instance, share their work with anyone within the hwdsb.on.ca domain, and still have it virtually invisible to anyone else in the world. Thus, it is an extra layer of security for your child’s identity.
